When i was reading, http://www.nasa.gov/exploration/home/antimatter_spaceship.html, i wondered if travels to different planets needs different spaceships, whit different things. (Francisco Portillo)

While i was reading my link again i found out that in that text i have one answer and it was that: tons of chemical fuel are needed to propel a human mission to Mars. This mean that a special spaceship is needed to travel to Mars, so a spaceship whit less fuel, will be use for close planets, or more tons of chemical fuel for distant planets. Also there are more spacecraft that are used for different things,different functions or to travel better to different planets.This spacecraft i found it´s called Orion. Orion's launch abort system, a "rocket on top of the rocket," is designed to ensure the safety of its astronaut crew by pulling the crew module away from it's booster rocket in the event of a booster malfunction, either while on the launch pad or during ascent to orbit. Special Spacecraft, of a cost of 500 million of dollars, was built by NASA with the assistance of private comapnies such as Martin Marietta and Hughes which contribute to build the spacecraft and special radar respectively. The spacecraft was taken in the cargo bay of the space shutter and later launched towrds Venus by an Atlas Centaur (spaceship) rocket, activated at a distance of more than 20 miles from the Shuttle, as a measure of safety for the astronauts in case of malfunction and potential explotion of large amounts of fuel. In one year this spacecraft arrive Venus (1990), and started to use it powerful radar to penetrate the thick layers of clouds of sulfur dioxide and began measuring the topography of the surface of the planet. Finally i found a intresting article about future spacecraft that talks about faster spacecraft (//**http://www.nasa.gov/vision/space/travelinginspace/future_propulsion.html**//).Spacecraft are still traveling at about the same speed that John Glenn did when he became the first American to orbit the Earth in 1962. One possible way to change that would be the Variable Specific Impulse Magnetoplasma Rocket (VASIMR). Not only would VASIMR allow for faster space travel, it would have some pretty incredible side benefits, as well. For example, NASA researchers believe that VASIMR would be able to travel to Mars much more quickly than a contemporary chemical-powered rocket, and then, once there,the would have to refuel on Mars for the return flight to Earth. The VASIMR engine could also even help protect astronauts from the dangerous effects of radiation during their trip. In the less-distant future, VASIMR could even help keep the International Space Station (ISS) in orbit without requiring extra fuel to be brought up from Earth. This could help the people to travel whit out any problem or risks. (437 words)
